fix: reject unknown with keys for the postgres and sqlite executors (#3440) by CJstate · Pull Request #3574 · dagucloud/dagu

CJstate · 2026-11-05T02:24:11Z

Summary

The postgres and sqlite executors silently drop unknown with keys — a typo like output_formt instead of output_format passes dagu validate and is ignored.

Close both executor config schemas with additionalProperties: false so unknown keys fail at DAG parse time, matching the other executors fixed for #3440.

The query text is folded into the step command by the action normalizer and import is a declared nested config, so closing the schema does not reject valid configurations. Verified all conformance/spec046_postgres and spec047_sqlite fixtures still load. The did you mean "output_format" ... hint comes from the registry's existing unknown-key suggestion.

Test plan

Added TestSQLRejectsUnknownWithKey: covers both executor types, the typo, the closest-key hint, and an accepted config.
go test ./internal/runtime/builtin/sql/ passes.

Github-Issue: #3440

Summary by cubic

Fixes the postgres and sqlite executors silently dropping unknown with keys — a typo like output_formt instead of output_format now fails at dagu validate time with a closest-key suggestion instead of being ignored (part of #3440).

Closes both executor config schemas with additionalProperties: false, matching the other executors fixed for Several actions silently ignore unknown with keys #3440. query folds into the step command and import is a declared nested config, so valid configurations still load.
Aligns the editor schema with the executors: adds isolation_level and shared_memory to SQLite, and drops max_open_conns, max_idle_conns, and conn_max_lifetime, which steps never read.
Adds TestSQLRejectsUnknownWithKey and conformance cases for both executors, and documents the rejection and suggestion in the postgres and sqlite specs.

Summary by CodeRabbit

Bug Fixes
- PostgreSQL and SQLite executor configurations now report errors for unrecognized settings instead of accepting them silently. When output_format is misspelled, the validation error suggests the correct setting.
- Configurations using recognized settings, including output_format and params, continue to validate successfully.

…agucloud#3440) The postgres and sqlite executors silently dropped unknown with keys, so a typo such as output_formt instead of output_format passed dagu validate and was ignored. Close both executor config schemas with additionalProperties: false so unknown keys fail at DAG parse time, matching xlsx, file, state, js, template, jq, mail, http, archive, s3, and redis. The query/import text is folded into the step command or the nested import config by the action normalizer, so it never reaches the executor config and closing the schema does not reject valid fixtures. Verified all conformance/spec046_postgres and spec047_sqlite fixtures still load. Add a regression test covering both executor types, the typo, the closest-key hint, and an accepted config.

Walkthrough

The PostgreSQL and SQLite configuration schemas reject undeclared properties. A test checks the hint for a misspelled key and confirms that a configuration using output_format and params validates.

Changes: SQL Config Validation

Layer / File(s)	Summary
Close SQL configuration schemas `internal/runtime/builtin/sql/config.go`, `internal/runtime/builtin/sql/config_test.go`	The PostgreSQL and SQLite schemas reject undeclared properties. The test checks the suggested key for `output_formt` and validates a configuration with `output_format` and `params`.

Explanation

The title names the main change: unknown with keys are now rejected for the postgres and sqlite executors. It follows the conventional fix: prefix and matches the summary, objectives, and test coverage. The title is 75 characters, within a reasonable length, and it includes the issue reference #3440.

Full details: Description check

Explanation

The description follows the repository template: it has a Summary, a summary of the change, and test plan details, and it references issue #3440. The Changes list and the Related Issues section are not in the template form. The Checklist is missing. The author did not mark any checklist items and did not state whether documentation was updated. The description says the spec documents were updated, which covers part of the documentation item. The description says tests were added and that the sql package test passes, so the test item is covered. It does not say whether the change was tested locally beyond the package test, or whether the code was self-reviewed. Most required content is present, so the check passes. The description also contains a generated cubic block that is not part of the template, but this does not block the check.

The SQLite executor passes isolation_level to the transaction it opens, and the docs list it for SQLite, so closing the schema without it rejected valid DAGs. Align the editor schema with the executors: add isolation_level and shared_memory to SQLite, and drop max_open_conns, max_idle_conns, and conn_max_lifetime, which steps never read and dagu validate now rejects.

Record in the PostgreSQL and SQLite specs that dagu validate rejects a with field the action does not define, and pin the error and its suggestion with conformance cases.

Thanks @CJstate! I pushed a small follow-up: SQLite still accepts isolation_level (the runtime uses it), the editor schema now matches, and I added the spec line plus conformance cases.

Verdict: safe to merge

Closing the postgres and sqlite executor schemas with additionalProperties: false is correct and consistent with the rest of #3440 (js, template, file, wait, state, … all use the same AdditionalProperties: &jsonschema.Schema{Not: &jsonschema.Schema{}} sentinel that forbidsAdditionalProperties in internal/executor/registry/schema.go:95 recognizes, so the "did you mean" hint fires).

Verification done by reading the code:

No valid config is rejected. Every mapstructure field on sql.Config (internal/runtime/builtin/sql/config.go:17) is declared in the matching schema: postgres gets advisory_lock, sqlite gets file_lock/shared_memory, both get isolation_level. query is never an executor-config key — commandAction("postgres", "query") / commandAction("sqlite", "query") (internal/spec/step_v2.go:92,101) delete it from with and move it to the step command before ValidateExecutorConfig runs at internal/spec/step.go:637. Nothing else injects keys into ExecutorConfig.Config for these types.
Editor-schema pruning is right. max_open_conns, max_idle_conns, conn_max_lifetime only exist as worker.postgres_pool.* server settings (internal/cmn/config/definition.go:441); no step code ever read them, and the docs site only documents them under worker.postgres_pool, not as step with keys. schemas/dag.schema.json is a symlink to the embedded copy, so TestDAGSchemaRepoCopyMatchesEmbeddedSchema stays satisfied without a second edit.
CI is actually green on HEAD. The six "failed" entries belong to run 43366237372, which was cancelled and superseded 4 seconds later by run 43366246516 (success) on the same SHA 3048584. All unit, conformance (ubuntu + windows), compatibility and lint jobs pass. I ran no local tests.
Earlier feedback is addressed. The only prior finding (CodeRabbit: sqlite schema missing isolation_level, which the runtime reads via BeginTransaction) is fixed in 869250934, with the editor schema aligned and a unit assertion covering transaction: true + isolation_level: serializable. The maintainer's own follow-up commits (869250934, 3048584) added the spec lines and conformance cases, and the review on this PR is already APPROVED. Nothing from that round remains open; no regressions introduced by the later commits.

Must fix before merging

Nothing.

Non-blocking follow-ups

Editor still won't flag the typo in the modern action form. action: postgres.query / sqlite.query steps validate their with against queryActionConfig (internal/cmn/schema/dag.schema.json:7326), which is additionalProperties: true; same for importActionConfig. So an IDE accepts output_formt while dagu validate now rejects it. harnessRunActionConfig shows the pattern that would close the gap (allOf of the executor schema plus the required primary input). Worth a separate PR, since query is not — and should not be — part of postgresExecutorConfig.
Nested with.import stays open. importConfigSchema has no additionalProperties, so a typo like input_fil is still silently dropped. Every ImportConfig field is already declared there, so closing it is a safe completion of #3440 for these two executors.
Release note. DAGs that currently carry ignored keys (max_open_conns & co., file_lock/shared_memory on postgres, advisory_lock on sqlite) will now fail to load rather than being ignored. That is the intent of the issue, but it is a user-visible breaking change and deserves a changelog line.

Performance and resource safety

None found by inspection; no profiling or load tests were run. The change is confined to parse-time schema metadata. Resolution stays cached per executor type behind sync.Once (internal/executor/registry/schema.go:135), so the added additionalProperties keyword costs one extra assertion per step build, not per run. unknownKeyHint/closestKey only execute on the error path and iterate ≤13 declared keys, so the Levenshtein work is bounded and never touches the hot path. No new allocations, goroutines, timers, file handles, connections or on-disk artifacts; nothing affects long-running server, scheduler or worker lifetimes. The two new conformance fixtures only run dagu validate, so they open no database.

Testing

Coverage is proportionate: a unit test at the registry boundary for both executor types (rejection, suggestion text, and an accepted config including isolation_level), plus binary-level conformance cases asserting the exact diagnostic, matching the wording already asserted in spec054_template and spec078_js_run. Both spec documents state the new rule. Thanks for picking this up and for keeping the fixtures aligned with the existing conventions.

yohamta0 · 2026-11-13T06:01:48Z

 var postgresConfigSchema = &jsonschema.Schema{
-	Type: "object",
+	Type:                 "object",
+	AdditionalProperties: &jsonschema.Schema{Not: &jsonschema.Schema{}},


Closing the top level is right, but the nested import object (importConfigSchema, shared by both executors) still has no additionalProperties, so with.import.input_fil remains silently dropped — the exact failure mode #3440 targets, one level down.

All fourteen ImportConfig mapstructure fields are already declared in that schema, so adding AdditionalProperties: &jsonschema.Schema{Not: &jsonschema.Schema{}} there would not reject any valid config; decision/config.go already closes its nested objects this way. Non-blocking — fine as a follow-up PR.

yohamta0 · 2026-11-13T06:01:48Z

          "type": "boolean",
          "description": "Wrap execution in a transaction."
        },
+        "isolation_level": {


These additions correctly bring sqliteExecutorConfig in line with the runtime schema, but that definition is only reached from the legacy type: sqlite form (line 3333). Steps written as action: sqlite.query are validated against queryActionConfig (line 7326), which is additionalProperties: true — so for the form most users write, the editor still won't flag output_formt even though dagu validate now fails on it.

harnessRunActionConfig shows a workable shape (allOf of the executor config plus the required primary input). Follow-up, not a blocker for this PR.

Thanks @CJstate for closing the postgres and sqlite schemas, so mistyped keys now fail with a suggestion instead of being silently dropped.
